Study of a radical-preferred frameworks
Although organic radicals can be used in various areas, including catalysts, sensors, and electrochemical energy storage, they are unstable meaning that it is difficult to develop materials containing radicals. Plus, once they cease to exist, they require a high level of energy for re-introduction. To address these limitations, Professor Jinhee Park intends to utilize radical π-stacks that are formed through a strategy of stabilizing a radical itself as a building block to further suggest a method for synthesizing a new radical-preferred frameworks.
The charge separation of radical materials increases their ability to adsorb guest molecules and can be used as a catalyst that enables the continued generation of ROS without the need for any irradiation. This project is expected to play a leading role in the development of a self-assembled organic radical-porous platform, which is a new area that is yet to be preempted elsewhere in the world.
Design of a superbasic dual functional organic catalyst and its application to asymmetric reactions
The project led by Professor Yunmi Lee aims to design and synthesize a dual functional chiral organic catalyst and apply it to the development of various asymmetric organic reactions. The development of an asymmetric catalysis that enables efficient synthesis of chiral compounds has constantly been sought after and establishing a new chiral catalytic system with excellent reactivity can translate into the development of reactions with high selectivity rather than a single reaction.
Products from asymmetric additions and fluoridation reactions are a highly value-added substance applicable to a wide range of areas, including organic synthesis, medicine manufacture and chemical materials. Fluoride compounds are also expected to play a pivotal role in new drug development as they account for 20% of new drugs currently under development.
Development of a cathode in aqueous rechargeable Li-ion batteries (LIB) with a 3.5 V potential window
Non-aqueous LIBs, demand for which has further increased since the declaration of carbon neutrality, have some serious flaws, such as their susceptibility to fires and their high price, neither of which can be improved without the development of more original and innovative batteries. The project led by Professor Hyeryung Byon aims to develop a stable and affordable aqueous LIB with a cycle performance and energy density that is comparable to those of non-aqueous LIBs, consequently developing an aqueous LIB with a potential window of approximately 3.5 V by reforming the interface between the aqueous electrolytic solution and the electrode.
As electrochemical reactions at the interface and the structure of an electrical double layer are still unknown research fields, findings from this project are expected to contribute to the commercialization of safe and affordable aqueous LIBs and to meet the needs from the ESS market, thereby exerting effects on both basic and applied research.
Realization of a multiple numeral system (quinary or higher) organic logic inverter using the structural control of a molecular switch
As semiconductor scaling reaches its limit due to issues, such as device instability caused by heat, the multiple numeral system logic circuit, which can perform the same operation with a smaller number of devices, is now emerging as a substitute. In this context, attention is being given to the development of a ternary inverter that can perform the same operation with 63% of the number of binary inverters.
The project led by Professor Daesung Chung aims to introduce a diarylethene molecular switch to a ternary inverter to adjust the resistance of each semiconductor through a light source with a certain wavelength, thereby realizing an inverter that can perform quinary or higher operations. Developing such an inverter that is capable of performing quinary or higher operations will enable the same operations with less than a half of the number of devices required for the existing semiconductors, consequently providing a breakthrough solution for the huge challenges that face semiconductor scaling, such as cost reduction and energy efficiency maximization.
